Can bio-organic fertilizer be mixed with chemical fertilizer?

The application of base fertilizer in autumn pays attention to all elements and total nutrition, that is, organic (long-acting) + inorganic (quick-acting) + beneficial bacteria (synergistic). The 17 elements needed for fruit trees must be complete, which can not avoid the mixed application of bio-organic fertilizer and inorganic chemical compound fertilizer.

Bio-organic fertilizer is not only rich in organic matter, but also added a large number of beneficial microbial active bacteria. Chemical fertilizer not only consumes the organic matter in the soil, but also can directly kill the beneficial microbial active bacteria in the soil. Without special processing and treatment, bio-organic and compound fertilizer can not be mixed together.

The principle of applying base fertilizer in autumn is "based on long-term slow release, adhere to biological organic, scientific formula fertilization". In order to improve soil, promote tree growth, prevent and control diseases and pests, and improve quality, many fruit growers generally realize the important role of bio-organic fertilizer. So they began to apply bio-organic fertilizer in an increased amount, but at the same time added ordinary compound fertilizer to the "first bombardment". As a result, not only organic matter was consumed, but beneficial microorganisms were killed. Resulting in a great waste of bio-organic fertilizer, more importantly, the underground roots of fruit trees are burned as "big roots without skin, small roots without hair", or even withered leaves.

Urea and general compound fertilizer are industrial raw materials for processing fertilizer, high tower granulation, low price, direct, excessive and concentrated application in orchard is easy to burn roots, especially can not be directly mixed with bio-organic fertilizer. However, using sulfur and HDDE as the main coating materials to wrap granular urea and chemical fertilizer to achieve the slow release of nitrogen, phosphorus and potassium and controlled loss fertilizer can be safely applied in the orchard, and can also be mixed with bio-organic fertilizer.

Sulfur-coated urea and sulfur-coated urea are inorganic coated slow-release fertilizers. Urea sulfur-coated urea is an encapsulated slow-release fertilizer made by wrapping sulfur and microcrystalline wax sealant on the outside of urea, which can release nutrients continuously and stably, meet the nutritional needs of crops, increase production and high quality. The color is unique and the fertilizer is nearly neutral. It is suitable for all kinds of soil and crops. The unique sulfur nutrient can control the nutrient release rate. There is a film on the surface of controlled-release fertilizer, which can be divided into sulfur-coated controlled-release fertilizer and resin-coated controlled-release fertilizer according to different coating materials. Take resin-coated controlled-release fertilizer as an example: there are micropores on the surface of the coating, which become larger or smaller due to thermal expansion and cold shrinkage, so it is also called "intelligent controlled-release fertilizer".

HDDE is a high-tech product rich in urease inhibitors, nitrifying enzyme inhibitors and nitrifying enzyme inhibitors. It can make the release rate of fertilizer coincide with the law of fertilizer demand of crops, truly realize that one application of fertilizer can meet the nutrients needed during the whole growth period of crops, and completely and effectively solve the deficiency of low utilization rate and serious loss of ordinary fertilizer. increase crop dry matter weight and yield, improve product quality and so on.

Slow release formula fertilizer and multi-element controlled loss fertilizer, sulfur coating or HDDE slow control loss factor were added to nitrogen, phosphorus and potassium, and Bacillus was coated with bio-organic fertilizer and Yijubao, which could be directly mixed with rest assured that it would not produce organic matter consumption and nutrient loss, and chemical fertilizer would not kill beneficial microorganisms. In the process of application, mixing soil is more conducive to fertilizer decomposition and conversion.
